1 14 Claims.

This invention relates to an apparatus for forming pointed corners in garments, such as collars.

Objects Among the principal objects which the present invention has in view are:To provide an apparatus having means wherein the corners of collars will be made permanently flat and pointed; to provide an apparatus having means whereby the two corners of a collar will be shaped and pointed simultaneously; to employ both heat and pressure and effect a shaping of the product during the application of the heat and pressure; to provide an apparatus which will perform the shaping of a collar having a uniform thickness throughout; to secure simplicity of construction and operation; and to obtain other advantages and results as may be brought out in the following description.

Description overlying a portion of the forming die and adapted to be brought down upon the same.

As here shown, operation of the pressure die 22 and creasing blade 23 is obtained by means of a treadle 24 connected by a link 25 to a first class lever 26, an intermediate part of which engages the upper end of the plunger 19. Link 25 attaches to one end of this lever 26, whereas the other end is fulcrumed as at 27 in a bracket 28 forming part of the head of the apparatus.

Preferably lever 26 provides a long arm-between the plunger 19 and the connection of the link 25, and provides a short arm between the plunger and the fulcrum 27, so that a moderate pressure exerted by the operator may apply a f considerable pressure to the plunger and the pressure ,die 22 and the creasing blade 23.

The forming die comprises in the present showing a fixed member 29 and a transversely movable member 30,v these parts being-so arranged and associated as to permit one edge of the collar 31 to engage an edge or abutment of the fixed member 29,, and the other edge of the collar to engage an edge or abutment o the movable member 30.

As seen inlth'e present showing, the fixed member 29 of the forming die is cut away as at 32 to receive the unfolded selvage or marginal end edge 33 of the collar 31 as well as the extreme bent-in end or tip '34 which'may be called the reinforced cornerof selvage'33. This tip is a triangular piece of the goods aligned with the line of folding of the margin or hem of the collar.

The movable die member 30 preferably provides a surface upon which the collar 31 may be placed flatwise in addition to engagement against the abutment above referred to.

The pressure die 22 is preferably shaped to conform with the desired collar corner surface of the collar 31 without engaging the raised portions of the forming die providing the abutments for shaping the collar.

Suitable means are provided for retracting or drawing the movable member 30 away from the fixed member 29 as the pressure die 22 is lowered. Said means in this instance may conveniently comprise the lowering of the creasing blade 23 simultaneously with the pressure die and forcing said blade between the dies. Said pressure die and creasing blade are preferably carried by the plunger 19 by beingattached thereupon as by a pair of threaded nuts 35, the lower portion of the plunger being screwthreaded to receive the same as clearly shown in Figure 4.

The pressure die 22 is suitably attached to the plunger, as by a stud 36 fitted within the plunger, there being a coil spring 37 within the plunger at the upper end of the stud. stud may have a keyway 38 to receive a pin 39 which extends laterally thereinto through the lower extremity of the plunger. The 'keyway is closed at its ends thereby limiting the movement of the stud and retaining the stud within the plunger.

As the plunger is being lowered, the crea line of the collar 31 and then passes downwardly between the fixed member 29 andthe movable member (see Figures 7 and 8).

as close together as they should be.

Said bracket has an opening 41 to permit a stud 42, to pass therethrough, said stud being secured to the bed.

At the outer end of the stud is a collar 43 against which one end of a heavy coil spring 44 rests, the other end of said spring bearing against the bracket 40.

When the corner ofthe collar 31 has been properly shaped and pointed, the plunger 19 is permittedto rise, thereby releasing the creasing blade 23 from between the fixed member 29v and the movable member 30, and simultataneously'thepressure exerted by the spring 44 against the bracket will cause the movable member to return to normal position until the next operation. '7 V a Means are provided in the movable die member 30 to limit the outward movement of said member, and in this instance I have shown a pair of pins 30a mounted in the bed 20 and extending upwardly through slotted portions 30b in the die member.

It is to be noted that to insure proper smoothing and creasing, introduction of heat is made tothe collar 31 being operated onby a heater element 45 (diagrammatically shown in Figure 1) attached to the under side of the bed 20 in proper association with the forming and pressure dies and the creasing blade.

As seen in Figure 9, I have illustrated the collar 31 in its final condition before rows of stitches (not shown) areapplied to the marginal edges. It is likewise to be understood that this collar is of a single thickness, and that the two corners have been properly shaped and pointed simultaneously and in one operation.
